A Texas real estate developer has filed plans to build an office building in North Charleston for an unidentified company that’s looking to bring more than 500 jobs to the region.

Dallas-based KDC is seeking permits on behalf of a previously disclosed economic development prospect code-named “Project Phoenix.”

A site plan submitted to the state Department of Health and Environmental Control shows an 80,000-square-foot office complex with nearly 700 parking spaces. The 16.5-acre property is part of the Ingleside tract, near U.S. Interstate 26 and Highway 78.

Charleston County Council’s Finance Committee is scheduled to vote Thursday on tax incentives being offered to the company that’s expected to occupy the building.

Project Phoenix first surfaced in September. It was described at the time in public documents as a Fortune 500 employer specializing in “customer care” and “technical support.”

The county said the planned $21 million capital investment would create 564 jobs over five years with average annual wages of $30,500.

The large number of workers and parking spaces suggest the building could house a call center or other back-office support operation.

The company’s identity will be disclosed after the incentives are approved. That requires three votes by County Council.

The S.C. Commerce Department also has been working to recruit the business. The state agency’s Coordinating Council for Economic Development last year approved a $55,000 grant to offset the costs of developing the Ingleside Boulevard property.

KDC officials did not respond to requests for comment. The firm typically does not discuss its projects publicly, an outside representative said Wednesday.

On its website, KDC said its specialties include developing new corporate headquarters and campus facilities. Citigroup, FedEx, Fluor and TRW are among some of its past clients. Its list of active projects shows office buildings for companies such as Toyota, Lennar and State Farm Insurance.
